The most common form of arthritis, osteoarthritis (also known as degenerative joint disease), occurs following trauma to the joint, following an infection of the joint or simply as a result of aging and the deterioration of articular cartilage. Structural classification is determined by how the bones connect to each other, while functional classification is determined by the degree of movement between the articulating bones. Make the changes yourself here! As the heart is found here, the great vessels associated with it are also found including the pulmonary arteries/veins, the superior vena cava and the aorta (as well as some of its proximal branches). This turn is known as the left colic flexure (or splenic flexure). It helps keep the body stable while walking by allowing the foot to roll in and out. The wave of excitation created by the SA node spreads viagap junctionsacross both atria, resulting inatrial contraction(atrial systole) with blood moving from the atria into the ventricles. 4% (33/868) 5. This rapid conduction allows coordinated ventricular contraction (ventricular systole) and blood is moved from the right and left ventricles to the pulmonary artery and aorta respectively. OCD usually causes pain during and after sports. They act collectively to stabilise the arches of the foot, and individually to control movement of the digits. The upper arm is located between the shoulder joint and elbow joint. These pacemaker cells can spontaneously generate electrical impulses. It serves two main functions: Separates the thoracic cavity from the abdominal cavity (the word diaphragm is derived from the Greek diphragma, meaning partition). The joint is classed structurally as a synovial joint, and functionally as a plane synovial joint.

However, the long head of the biceps brachii is one of the more common tendons to rupture.. It forms the floorof the cubital fossa. The atrioventricular bundle (bundle of His)is a continuation of the specialised tissue of the AV node, and serves to transmit the electrical impulse from the AV node to the Purkinje fibres of the ventricles. [21], The English term articulation is derived from Latin articulatio. A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole.

The rate at which the SA node generates impulses is influenced by the autonomic nervous system: After the electrical impulses spread across the atria, they converge at theatrioventricular node located within the atrioventricular septum, near the opening of the coronary sinus. They are two separate endocrine glands, with different embryological origins: The cortex and medulla synthesise different hormones. Most of the lymph from the superiormesenteric and inferior mesenteric nodes passes into theintestinal lymph trunks, and on tothe cisterna chyli -where it ultimately emptiesinto the thoracic duct.

Arthropathies are called polyarticular (multiarticular) when involving many joints and monoarticular when involving only a single joint. Although this forms part of the functional joint, the true anatomical subtalar joint consists only of the surfaces mentioned above. [3], The English word joint is a past participle of the verb join, and can be read as joined. The right gland is pyramidal in shape, contrasting with the semi-lunar shape of the left gland.
